Abstract
An implantable cervical plate assembly for stabilization of two adjacent spinal vertebras includes a cervical plate and one or more bone fasteners. The cervical plate comprises an elongated asymmetric body having a first straight side surface, a second contoured side surface opposite to the first side surface, front and back surfaces and top and bottom surfaces. The elongated asymmetric body comprises one or more through-openings extending from the front surface to the back surface of the elongated asymmetric body. The one or more bone fasteners are configured to be inserted through the one or more through-openings, respectively, and to be attached to locations in the spinal vertebras, thereby attaching the cervical plate to the spinal vertebras. The through-openings comprise a first diameter at the front surface of the elongated body, a second diameter at the back surface of the elongated body and a third diameter in the area between the front and back surfaces of the elongated body. The first diameter is smaller than the third diameter, thereby forming a lip at the top of the through-openings. The third diameter is larger than the second diameter and the first diameter is larger than the second diameter, thereby forming a groove within the perimeter of the inner wall of the through-openings. The bone fasteners comprise a threaded main body and a head. The threaded main body comprises threads for engaging the spinal vertebras and the head comprises one or more flexible structures configured to be flexed and inserted into the groove and then unflex and remain captured within the groove.
